1 Introduction and applications
The bubbleFoam solver is a two-phase solver based on the Euler-Euler two-fluid methodology [1, 2, 3, 4, 10], suitable to compute dispersed gas-liquid and liquid-liquid flows. In the Euler-Euler two-fluid approach, the phases are treated as interpenetrating continua, which are capable of exchanging properties, like momentum, energy and mass one with the other. Typical applications of the two-fluid approach, as implemented in bubbleFoam, are:
- bubble columns
- stirred tank reactors
- static mixers
